Critical Thinking Questions
29. For whom would an appreciation of the structural characteristics of the human heart come more easily: an alien who lands on Earth, abducts a human, and dissects his heart, or an anatomy and physiology student performing a dissection of the heart on her very first day of class? Why?
A: The alien would. They have no frame of reference for what human anatomy looks like.
31. The ovaries and the testes are a part of which body system? Can these organs be members of more than one organ system? Why or why not?
A: Reproductive and Endocrine. These organs work in tandem with both the Reproductive and Endocrine system to produce and secrete hormones.

35. On his midsummer trek through the desert, Josh ran out of water. Why is this particularly dangerous?
A: Water is considered the most critical nutrient for the human body. The body’s functional chemicals are dissolved and transported with water. Water is also the largest component of cells, blood, and fluid between cells. Water also helps regulate our internal temperature, which would be necessary to have if you were in a hot desert.
37. What regulatory processes would your body use if you were trapped by a
blizzard in an unheated, uninsulated cabin in the woods?
A: Shivering which causes random muscle movement to generate heat. The body will also break down stored energy to generate heat. 39. If a bullet were to penetrate a lung, which three anterior thoracic body cavities would it enter, and which layer of the serous membrane would it encounter first? A: Ventral, Pleural and the mediastinum. The Parietal membrane.
41. Explain why ultrasound imaging is the technique of choice for studying fetal growth and development.
A: It gives real time imaging and is also the least invasive techniques which uses no radiation.
